This invention relates to vacuum cleaner brushes.

The general object of the invention is toprovide a novel detachablevacuum cleaner brush..

A more specific object of the invention is to provide a vacuum cleanerbrush which is mounted in a novel manner on a vacuum cleaner nozzle.

Another object of the invention is to provide a swivelly mounted vacuumcleaner brush which includes a novel means for holding the brush inplace. v

Other objects and the advantages of my invention will be apparent fromthe following description taken in connection with the accompanyingdrawing, wherein:

Fig. 1 is a side elevation of a vacuum'cleaner showing my inventionattached thereto;

Fig. 2 is a side elevation with parts in central section showing a brushembodying the features of my invention;

Fig. 3 is a top plan view of the brush;

Fig. 4 is asection taken on line 4-4 of Fig. 2;

Fig. 5 is a side elevation showing the nozzle with the brush removed;and

Fig. 6 is a sectional view through a modified form of brush.

Referring to the drawing by reference characters I have shown myinvention as embodied in a vacuum cleaner which is indicated generallyat I0. -As shown the cleaner l includes a .housing H in which a suitablemotor and fan may be mounted. The housing is provided with a closuremember |2 from which an ofiset conduit l3 extends. This conduit includesa swivel I4 to which one end of a hose I is secured. The hose is'alsoconnected by a, swivel IE to a rigid handle l1.

The handle I! is detachably secured by a coupling member l8 to a swivelmember l9 which has a flange thereon. This flange 20 has a plane .endface' 2| which engages a plane end 22 on a nozzle 23'. 4

A removable collar 24 surrounds the flange 20 and engages the face 22and is secured ,in place by fastening means shown as screws 25. Thecollar 24 includes an inwardly directed flange 25 which engages theflange 2i. Theconstruction is such that the nozzle 23 is rotatable aboutthe swivel member l9.

r In order to lock thecollar 24 in a desired posi-, ti'on relative totheswivel I9 I provide the coldirection engages the swivel ii! to retainthe parts in adjusted position.

My improved brush is indicated generally at 30. This brush includes abody 3| which may be made of wood and which is elongated as shown inFig. 3. The brush is provided with a rabbeted portion 32 which is of thesame configuration as that of the end 33 of the nozzle 23. A resilientwasher 34 is fitted in the rabbet 32 and is engaged by the end portion33 of the nozzle 23 as shown in Fig. 4.

The body 3| of the brush has a pair of clamp members 35 pivotallysecured thereon by screws 36. These clamp members 35 include'fingerengaging portions 31 beneath which engaging faces 38 are disposed. Theseengaging surifaces 38 engage a portion 39 on the nozzle 23 as shown inFig. 2. The construction is such that when the clamp members 35 areturned away from 20 the nozzle the latter may be removed from the brush.

The brush is provided with a central aperture 40 which connects with atapering elongated longitudinal groove 4| as shown in Fig. 2. The 2bristles 42 of the brush surround the aperture 4| and are arranged inthe base of the rabbet 43.

The periphery-of the body 3| is providedwith a groove 44 which receivesa flange 4 on a rubber guard or bumper 46 which extends entirely abovethe brush.

In use the motor in the cleaner is started and the. operator moves thebrush over the surface to be cleaned. The brush lhosens the dirtwhich'is drawn into the dust bag in the cleaner. Due to the swivelaction of the nozzle the brush may be moved into places otherwiseinaccessible. When it is desired to use a rigid brush the, screw 21 istightened. When the operator wishes to remove the brush 23 the clampmembers are released and the nozzle removed. The nozzle may be then usedwithout the brush. f

In Fig. 6 I show a modification of my invention which includes a brush50 haw'ng a central passageway 5|. The brush 5ll is provided withbristles 52 arrangedabout the passageway 5| and cleaner brush which canbe readilymanufa tured and which is highly. eilicient in use.

Having thus described my invention, I claim: For. use, with a vacuumcleaner, a combined brush member and nozzle member, said nozzle memberhaving a peripheral flange thereabout.

said flange including a downwardly extending edge portion, said brushmember including a body having a rabbeted portion therein receiving saidflange, said flange and said rabbeted portion having parallel sides andlike semi-circular ends whereby theiposition of the brush may bereversed, said rabbeted portion having a flat lower face, a gasketengaging said face, said downwardly extending edge portion on saidflange engaging the outer portion of said gasket, a pair of metalclamping members pivotally mounted on said brush member at each endthereof, each of said clamping members including an upwardly directedfinger engageable portion and having a lower face to engage the nozzlemember, said nozzle member having notched portions thereon receivingsaid clamping members.
